Techniques for generating video tracks based on user preferences

Abstract

In various embodiments, a manifest customization application generates presentations of media titles for playback. The manifest customization application selects a first set of video streams from multiple sets of video steams that are associated with a media title and included in a media package video streams based on a first preference associated with a user. The manifest customization application selects a first set audio streams from multiple sets of audio streams included in the media package based on a second preference associated with the user. The manifest customization application generates a recommended presentation based on the first set of video streams and the first set of audio streams. The manifest customization application generates a manifest file that allows the media title to be played back in accordance with at least the recommended presentation.

       9. The computer-implemented method of  claim 1 , wherein generating the manifest file comprises generating a description of a video track that specifies at least one of a different bitrate, a different resolution, a different quality score, or a different locator for each of one or more video streams included in the video track. 
     
     
       10. The computer-implemented method of  claim 9 , wherein a first locator for a first video stream included in the video track comprises a universal record locator associated with a first segment included in the first video stream. 
     
     
       11. One or more non-transitory computer readable media including instructions that, when executed by one or more processors, cause the one or more processors to generate presentations of media titles for playback by performing the steps of:
 selecting a first set of video streams from a plurality of sets of video streams based on a first preference associated with a first user, wherein the plurality of sets of video streams are associated with a media title and are included in a media package;
